Mute Swans - Invading Michigan's Waters

Mute swans are an invasive non-native species that pose a growing threat to native animals, habitat and people. Their numbers are well above an acceptable range, requiring the DNR to increase management efforts. The DNR needs your help to decrease this invasive population.

Protecting our Trumpeter Swan
The mute swan poses a significant threat to the continued success of the native trumpeter swan, a threatened species in Michigan. This threat will continue as long as the population of mute swans is not drastically reduced. Learn more about trumpeter swans.
